Overview

Orthovinyl lamination resin is a vinylester-based resin that is easy to process and can be used to fabricate thin-walled, stable laminates. Due to its structure, it bonds to carbon fibre more effectively than an acrylic resin. This achieves a high degree of stiffness at a low  laminate wall thickness, which falls between that of an acrylic resin and that of an epoxy resin. Nevertheless, Orthovinyl can be processed as quickly and easily as an acrylic resin. The standard Ottobock 617P37=0.150 hardener can be used.

Benefits at a glance:

• The laminate achieves a verified biocompatible state following sufficient tempering (see processing instructions)
• The resin exhibits a slightly yellow tinge in the liquid state which is not, however, visible in the laminate
• As with an acrylic resin, the setting time can be reliably determined based on the added hardener and the temperature
• Higher degree of stability than an acrylic resin due to better bonding to the reinforcement fibers
• Very easy to sand
• Excellent balance between matrix and reinforcement material
• Can be colored with Ottobock pigment pastes
• Small number of layers possible
• Very good impregnation, especially of carbon fibers
